Intermittently, there are threads on Coconut oil and apologies if this repeats anything said before. I've tried to speed-read previous posts but am up all hours at mo, battling really nasty chest infection with one mother, so might well have missed something:-
I started using Coconoil a little while ago. I can't seem to get the sort of quantities into either mother, that are recommended for dementia (ie. several tbspns - Maccare has written about this) - without it having an explosive impact on digestion! But I am using between 1/4 tspn and 1 tspn a day in porridge to keep gut motility on track and ward off constipation and for that, it seems to be working really well. Possibly, our two mothers are too far advanced for Coconoil to have any positive impact on dementia.
However, I'm cooking more with it for the family generally. (Makes fantastic roast veg). My younger son pointed out that it is very high in saturated fat - I recently checked this out - he's right, but there seems to be a difference between refined (with the risk of hydrogenated and trans fats) and organic. Organic coconoil seems to be fine but sadly, you have to pay the higher organic price for it. Go to kelkoo perhaps to shop around for offers. Having said that, a little coconoil goes a long way - and you can use it for wrinkles and furniture!
Some people seem to suggest that you should be looking for the most expensive oil you can find rather than the cheapest. I don't know about that, but it's clear that not all oils are equally effective (for those that benefit at all).
